I'm trying to create kubernetes cluster, but whatever mode I try in the end kubectl fails with

The connection to the server ASFASF.da2.ap-northeast-1.eks.amazonaws.com  was refused - did you specify the right host or port?

I already tried:

1) Install with Terraform ( following all official docs )
2) Manual EKS installation through UI
3) Install with eksctl tool

It all ends with this error, I already tried to tweak all possible subnets, roles, users, routes, dns, basically everything what might help in other SA threads / github issues, but no success..

What am I missing?

inb4 yes I tried update kubectl config or specify role there
